GAS H EATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 622,558, dated April 4, 1899.

Application tiled April15, 1896. Serial No. 587,5 82. (No model.)

To cir/ZZ whom t may con/cern:

Beit known that I, BERNARD STEcHER, a citizen oi the United States,residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improve mentin Gas Heating-Stoves, of which the following is a specification.

My invention relates to the improvement of heating-stoves which employ gas as a fuel, and has particular relation to stoves adapted for burning natural gas.

The object of my invention is to produce a stove of this class embodying an improved construction and a novel arrangement of parts whereby it is rendered highly efficient, as well as durable and inexpensive. These objects I attain in the manner illustrated in the acp companying drawings, in which- Figure 1 is a view in perspective of my improved stove. Fig. 2 is a plan view, and Fig. 3 is a central vertical section.

Similar letters refer to similar parts throughout the several views.

a represents the body of my improved stove, which may be formed of sheet metal or other suitable material and which may be in the form of the square or oblong casing shown. Of this casing, h represents the vertical front plate and c the vertical back plate. d represents a suitable base upon which thecas-v As indiing or body a is designed to rest. cated in the drawings, the front plate h is provided with parallel rows of openings h', while beneath said openings and in the lower part of said front plate are provided oblong openings or windows b2, which may be lled with isinglass or other suitable transparent material. The lower portion of said plate b is also provided with one or more lighting-openings which are adapted to be covered by pivoted doors h3.

Between the front plate b and back plate c are arranged vertical partition-plates c, e', and e2, the latter being separated, as shown, and resulting in the formation between the same of internal .passages f, g, and h. The

rear partition-plate Z2 is at such distance from the back plate c as to result in the formation of an air space or chamber t' between the same. As indicated Vin the drawings, the rst or front partition e extends downward a sufiicient distance in the casing to meet Va bottom plate 7c, which is arranged, as shown, in the lower portion of said casing. The upper end ot' this forward partition-plate e terminates a short distance from the top of the casing. The second or middle partition-plate c eX- ten'ds from the top of the casing to a point a short distance above the bottom plate tgwhile the rear partition-plate ea extends from the bottom plate k to a point in line with the top of the forward plate e, this arrangement resulting, as will readily be seen, in' a communication of the passages being formed at the upper and lower portions of the casing alternately. y

Leading outward from the upper end por tion of the rear passage h is an outlet-pipe m, and leading into the lower portion of the air-v chamber i is an inlet-pipe n, the latter preferably leading from outside the house or to a basement or other source of cold-air supply.

o represents transverse air-pipes, which are arranged at desirable intervals within the casing, said pipes leading through the plates e2, e', and e and communicating with the open ings b in the front plate b.

Supported in the lower and forward portion of the casing, beneath the space which is be tween the front plate b and partition-plate e, is a cylindrical burner p, the latter having burner-perforations on its upper 'side in the usual manner and having a gas-supply pipe q leading thereto.

The burner p is supported upon the bottom of the body or casing of the stove and sustains the forward end of the bottom plate 7o, thereby serving to prevent twisting or warpA ing of the partitions and at the same time ettectually closing the space between the eXi tremity of the bottom' plate 7o and the front wall of the casing. The gas-pipe q, which, as stated, is designed to supply gas to the burner, communicates directly with a transverselyL triangular-shaped gas-chamber fr, which ex tends upwardly through the top plate of the base d and through the bottom wall ot' the body or casing a, where it comm unicates with apertures s,piercing the bottom of the burner. It will be noted that a chamber t is formed between the bottom plate Zo and the bottom of the casing, which chamber extends rearwardly underneath the hot-air passages g and 7L and the cold-air chamber t', the provision ICO of this chamber serving to prevent downward radiation and to initially heat the inflowing current ot cold air as it enters through the inlet-pipe n. In the preferred form of my in- Vention the base dis provided with upwardlyextending flanges u, which serve to .secure the body ct upon the base, the triangular form ot the chamber r serving as an additional means for preventing the accidental dislocation of the body from the base.

From the construction and arrangement of parts herein described itwill be seen that the flame from the burner will be directed into the lower portion of the passage f and that the heat and products of combustion which rise in said passage will, following the arrows, pass through the passages g and h and out through the outlet-pipe fm. ln this manner it is obvious that not only will the various plates and partitions which form the stove become heated, but the pipes o, about which the heat passes, will have imparted thereto a high degree of heat. It will thus be seen that the cold air which is drawn into the airchamber through the pipe fnwill pass through the heated pipes and heated interior of the stove out into the room through the openings b.

From the construction and operation which I have described it will be seen that a constant current of fresh air will be subjected to the heat which is generated at the burner and that the air thus heated will be mingled with the air in the room in which the stove is used. It will also be seen that 4the sinuous path followed by the heat and products of combustion is such as to retain the heat the desired length of time within the stove. The

heat-passages of my improved stove are so arranged as to prevent the products of combustion escaping into the room, thereby insuring a comparatively pure atmosphere.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is

l. Inagas-stove of the character described, the combination with a body or casing provided in its rear wall adjacent to its top and bottom respectively with outlet and inlet openings, of a bottom plate extending from the rear wall at a point intermediate of the inlet-opening and the bottom of the casing, an upwardly-extending partition at the extremity of the bottom plate and terminating below the top of the casing, a second upwardly-extending partition supported by the bottom plate and likewise terminating below the top of said casing, a downwardly-extending partition depending from the top of the casing intermediate of the other partitions and terminating above the bottom plate, a partition extending between the rear wall of the casing and the adjacent partition and in close proximity to the outlet-opening, a series of pipes located intermediate of the lastnamed partition and the bottom plate and extending horizontally through the several partitions and through the front wall of th'e casing, a cylindrical burner located at the bottom of the casing and supporting the front end of the bottom plate, and meansforsupplying air to the burner, substantially as speciiied.

2. Ina gas-stove of the character described, the combination with'a base provided with vertical flanges, of a casing provided with internal air-passages and passages for products of combustion, a burner Within the casing defining the bottom of one of the productpassages, a triangular chamber extending through the top plate of the base and the bottom wall of the casing and communicating with the interior of the burner, and a gassupply pipe extending into the base and communicating directly with the triangular chamber, substantially as speciiied.
